brakes operate hydraulically from the brake pedals
boosted by the low pressure hydraulic. There is no
separate brake fluid in the brake system. The system uses
transmission/hydraulics oil. The system is equipped with a
pressure accumulator, which makes it possible to brake
after the engine has stopped. When braking on the road
the friction discs will be cooled with oil spray. When both
brake pedals are depressed the front wheel drive is
engaged automatically (4WD indicator lamp lights on
instrument panel) in order to provide braking function at
the front wheels. The pedals can be connected together
and used as running brakes or separated and used
individually as steering brakes. The brakes can be
adjusted by means of adjusting nuts which are fitted on
the rear axle.
The parking brake is electro---hydraulic and is controlled
with a shuttle lever. When engaging the parking brake
(parking brake and 4WD indicator lamps light on
instrument panel), the pressure exhausts from the cylinder
operate the parking brake and a strong spring engages
the tractor brakes. At the same time the control unit
disengages the transmission. With this system the tractor
brakes are always on when the engine is not running.
